3. Consider a contintous unity feodback system which has forward transfer function as,

$$ G(s)=\frac{1}{s^{3}+13 s^{2}+40 s} $$

the desired specifications for this system are Settling Time: \(2 \mathrm{~s}\) and Percent Overshoot: \(10 \%\).

(a) Design a lead compensator for the digital system to have these specifications. In order to obtain digital controller use following approximation methods, Differencing Methods, Pole-Zero Matching, Bilinear Transformation (Tustin). Take sampling period as \(T=0.01\) s.

(b) Simulate your digital controllers with \(G(s)\) using Matlab Simulink.

Answer #1

Electricity cost= 120


Material cost= 3000*$5= 15,000


Labour cost= 4*5 days*8 hours*$18 = $2880


because the material cost is most significant,


Hence, Attention should be on Material cost.
